Moreover, the $ (C , \beta_{n})$-means $\sigma_{2^n}^{\beta_{n } f$ of the function $ f \in L_{1} $ converge a.e. to $f$ for $ f \in L_{1}(I^2) $, where $I$ is the Walsh group for some sequences $1&gt; \beta_n\searrow 0$.</p&gt;}, number={3}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Abu Joudeh , A.
